Continuous random variables are defined from a standard form and may
require some shape parameters to complete its specification. Any
optional keyword parameters can be passed to the methods of the RV
object as given below:

Frozen RV object with the same methods but holding the given shape,
location, and scale fixed.

Notes

Truncated Normal distribution.

The standard form of this distribution is a standard normal truncated to the
range [a,b] — notice that a and b are defined over the domain
of the standard normal. To convert clip values for a specific mean and
standard deviation use a,b = (myclip_a-my_mean)/my_std, (myclip_b-my_mean)/my_std
